# 字体索引
|
||
|
||
一个小示例，它展示了对字体表的各种索引是如何相互关联的。主要是为MPL开发商.。
|
||
|
||
输出：
|
||
|
||
```python
|
||
(6, 0, 519, 576)
|
||
36 57 65 86
|
||
AV 0
|
||
AV 0
|
||
AV 0
|
||
AV 0
|
||
```
|
||
|
||
```python
|
||
import matplotlib
|
||
from matplotlib.ft2font import FT2Font, KERNING_DEFAULT, KERNING_UNFITTED, KERNING_UNSCALED
|
||
|
||
|
||
fname = matplotlib.get_data_path() + '/fonts/ttf/DejaVuSans.ttf'
|
||
font = FT2Font(fname)
|
||
font.set_charmap(0)
|
||
|
||
codes = font.get_charmap().items()
|
||
#dsu = [(ccode, glyphind) for ccode, glyphind in codes]
|
||
#dsu.sort()
|
||
#for ccode, glyphind in dsu:
|
||
# try: name = font.get_glyph_name(glyphind)
|
||
# except RuntimeError: pass
|
||
# else: print('% 4d % 4d %s %s' % (glyphind, ccode, hex(int(ccode)), name))
|
||
|
||
|
||
# make a charname to charcode and glyphind dictionary
|
||
coded = {}
|
||
glyphd = {}
|
||
for ccode, glyphind in codes:
|
||
name = font.get_glyph_name(glyphind)
|
||
coded[name] = ccode
|
||
glyphd[name] = glyphind
|
||
|
||
code = coded['A']
|
||
glyph = font.load_char(code)
|
||
print(glyph.bbox)
|
||
print(glyphd['A'], glyphd['V'], coded['A'], coded['V'])
|
||
print('AV', font.get_kerning(glyphd['A'], glyphd['V'], KERNING_DEFAULT))
|
||
print('AV', font.get_kerning(glyphd['A'], glyphd['V'], KERNING_UNFITTED))
|
||
print('AV', font.get_kerning(glyphd['A'], glyphd['V'], KERNING_UNSCALED))
|
||
print('AV', font.get_kerning(glyphd['A'], glyphd['T'], KERNING_UNSCALED))
|
||
```
